Connecting the AC/DC Adapter
Besides using four AAA-sized batteries as a power source, the DO 110 meter can
also operate from the power mains using an AC/DC power adapter. This is extremely
useful if you have an A.C. power source available (e.g. laboratory).
Before plugging in, switch off the meter and the power source of adapter. This is a
safety precaution that should be adhered to safeguard your meter.
1. Switch off the meter and power sources.
2. Select the correct AC/DC Adapter which matches your input mains voltage.
3. Select the correct output voltage of the AC/DC adapter. (Output Voltage: 9 to
15 V DC, Current: >=50 mA).
4. Gently insert the power adapter D.C. jack into the meter power socket.
5. Switch on the power source of the adapter followed by the meter.
3.4
Connecting the RS232C Cable
The DO 110 meter provides a RS232C output for you to
transmit your readings either to a printer or a computer via
a cable. This is useful in instances where the meter is used
for continuous monitoring of a certain process or
experiment. Data output to the printer or the computer can
then be evaluated.
The data is output in the ASCII format. This format allows
the data to be imported by a wide variety of software that
read ASCII data (e.g. Microsoft’s Excel, Lotus, Quattro-pro
etc.). A complimentary Data Acquisition Software (DAS) is
provided and it captures data transmitted into an ASCII
file for later use.
Figure 4: Location of
RS232C
1. Open the printer port cover located at the bottom
end of the meter. Do not use excessive force when doing this. See Figure 4.
2. Noting the orientation of the RS232C connector, plug the male connector into
the RS232C port of the meter.
3. Fasten the RS232C connector by fastening the two screws at the side of the
male RS232C connector.

CALIBRATION
Important Information on Meter Calibration
The amount of oxygen dissolved in water will depend on its temperature, atmospheric
pressure and its salinity. While the pressure and salinity values are manually entered
into the instrument, the temperature is being measured by the probe. It is therefore
very important that the temperature is calibrated if necessary prior to the DO
calibration.
The measurements of % Saturation of DO will linearly affect the measurement for DO
in mg/L. Hence calibration in % Saturation of DO should be carried out first. This is
described in the following section.
Before calibrating, press MODE key to select the correct measurement mode. There
are 2 measurement modes for DO: mg/L or ppm, and % Saturation.
NOTE: All new calibrations will automatically over-ride existing calibration values.

4.2
CyberScan DO 110
Temperature Calibration
DO in mg/L is dependent on temperature, so it is first
necessary to calibrate or verify the temperature reading. The
temperature sensor is part of the DO probe and the “ATC”
annunciator will light up on the LCD screen once the probe is
connected correctly to the meter.

DO Calibration (with ATC) –% Saturation Mode
Dissolved Oxygen exact calibration value depends on barometric pressure. The
meter is set to a factory default of 760 mm Hg, which results in a
calibration value of 100% saturation in air.
NOTE: If the barometric pressure setting has been changed
from 760 mm Hg, the calibration value in air will automatically
adjust to a value other than 100%. The adjusted value will be
correct for the new barometric pressure setting. See Section

The amount of oxygen dissolved in a liquid will depend on its
temperature, pressure and salinity. It is therefore very important
to set these parameters correctly before attempting to do a
calibration.

Dissolved Oxygen Probe
10.1 Dissolved Oxygen Principle
The probe is a galvanic measuring element which produces an output proportional to
the oxygen present in the medium in which it is placed. The galvanic probe design
lets you take measurements immediately – without the typical 15 minute wait of other
dissolved oxygen probes.
The probe consists of two parts:
• An upper part consisting of an anode, a cathode, and cable.
• A lower part consisting of a membrane cap, membrane, and electrolyte solution.
Oxygen diffuses through the membrane onto the cathode, where it is consumed. This
process produces an electrical current which flows through the cable to the meter.
The electric current produced is proportional to the oxygen that passes through the
membrane and the layer of electrolyte. This makes it possible to measure the partial
pressure of oxygen in the sample at a given temperature.
Since the DO in the sample is consumed by the cathode it is essential that a new
sample must flow past the membrane of the probe to prevent the occurrence of false
readings. The probe uses very little oxygen for its measurement. This enables it to
function correctly with liquid movement as low as 2.5 cm/sec.
The permeability of the membrane to oxygen varies greatly with temperature.
Therefore compensation is needed for this variation. The DO probe comes with an inbuilt Temperature Compensation for the membrane variation.
10.2 Probe Care
Under typical operating conditions, the probe should last for several years. Proper
care and maintenance will help you receive the maximum probe life and ensure more
accurate readings.
Since any deposits on the membrane surface act as a barrier to oxygen diffusing
through the membrane, the membrane must be cleaned at regular intervals to assure
maximum reliability.
After using the probe, rinse the probe in clean water and wipe it with a soft cloth or
paper to avoid any hardening of deposits. If growth develops on the probe, use a
disinfecting chemical to clean.
NOTE: Although the membrane is strong and not easily damaged, wipe it
gently while cleaning it. If the membrane is damaged or torn, the probe
will no longer function.
There are no special probe storage requirements.

CyberScan DO 110
10.3 Membrane Housing Replacement
Replacement of the membrane cap housing/ membrane is
required only when you cannot calibrate the probe, or if the
membrane is damaged.
Typical membrane damages are punctures or wrinkles caused
during measurements or cleaning.
Your new DO probe comes with replacement membrane
housing. To order more replacement membrane housing, see
the “Accessories” section page.
10.3.1 To replace the membrane cap (with pre-installed
membrane) 1. Replacement is much easier with single membrane
housing. Unscrew the old membrane cap housing.
2. Hold the probe under hot running water and brush away
the white oxide on the cylindrical anode with a stiff
plastic brush – do not use metal cleaning material.
3. If the cathode has any deposits, remove them with a
light scouring powder. Do not polish the cathode.
4. Fill the new membrane cap housing with electrolyte
solution and inspect the bottom for leaks. If the solution
drops are leaking from the membrane, use new cap
housing.
Figure 33: Positioning
of O-ring & membrane
5. If the assembly is leak-free, fill the membrane cap housing with electrolyte to
the brim.
6. Tap the side of the housing gently to remove any air bubble that may be
sticking to the membrane.
7. Screw the cap onto the probe. Excess electrolyte will drain out.
8. Replace probe guard.
9. Calibrate the probe (see section 4) after the % saturation readings have
stabilised.
46
Instruction Manual
CyberScan DO 110
10.4 Membrane/O-ring Replacement (Optional Procedure)
It is recommended only experienced service personnel can perform this procedure.
This procedure is OPTIONAL, and should only be performed if you have new
membrane and O-ring. You are also required to have a membrane installation tool.
These items are available as optional accessories in the “Accessories” section.
Pull off the probe guard.
1. Unscrew the membrane cap from the probe.
2. Hold the probe under hot running water and brush away
the white oxide on the cylindrical anode with a stiff
plastic brush – do not use metal cleaning material.
3. If the cathode has any deposits, remove them with a
light scouring powder. Do not polish the cathode.
4. Using the installation tool, unscrew and remove the
membrane lock from the membrane cap. See Figure 35
on the following page.
5. Remove the membrane and O-ring. Discard both.
6. Rinse the membrane cap and membrane lock in tap
water.
7. Install a new O-ring inside the membrane cap.
8. Install a new membrane. Make sure the membrane
covers the O-ring all around its circumference.
Figure 34: Positioning
of O-ring & membrane
9. Using the installation tool, screw the membrane lock
back into the cap. Tighten the lock firmly over the membrane and O-ring, but
do not over tighten.
10. Inspect the membrane for wrinkles. If wrinkles exist,
remove the membrane and repeat steps 8 – 11.
Close
11. Fill the membrane cap with water and inspect the
bottom for leaks. If water drops are leaking from the
membrane, re-seal the membrane on the O-ring
(repeat steps 8 – 11, for membrane replacement only).

14. Replace probe guard.
15. Calibrate the probe (see section 4) after the % saturation readings have
stabilised.
Note: Membranes can only be used once. When a membrane cap is
screwed onto the probe, the membrane is stretched by the cathode. If the
same O-ring and the membrane is used a second time it will not fit
perfectly onto the cathode. This will result in erratic readings.
10.5 Electrolyte Solution
The electrolyte solution in your probe’s cap will deplete on usage and will need to be
replaced periodically.
Your new DO probe comes with accessories of one replacement electrolyte solution
and a spare membrane cap. The replacement electrolyte comes premixed and ready
to use. To order more electrolyte solution, see “Accessories” section.

TROUBLE-SHOOTING
When experiencing difficulties with the equipment, keep in mind of the following:
1. Check for the obvious, such as physical condition of the probe, any signs of
damage to the cable, power and signal connections etc.
2. Determine whether it is the probe, meter or the surrounding environment that
is causing the problem.
The following troubleshooting table identifies most of the problems likely to occur:
Problem
Nothing is displayed when
the ON/OFF key is
selected.
Fluctuating readings when
probe is shaken or bumped
lightly or when membrane is
touched.
Probable Causes
Solution
Batteries not in place.
Insert batteries.
Batteries (+ & - poles) not in
correct polarity.
Re-insert batteries in the
correct polarity.
Weak batteries.
Replace batteries or attach
AC adapter.
Probe has lost electrolyte – a
sloshing noise will be heard
when the probe is shaken.
Unscrew the membrane cap,
discard the electrolyte,
membrane and O-ring.
Torn or damaged membrane.
Dry the internals of the
probe, especially the cathode
with a soft cloth.
Wet connections in the wiring or
within probe. See Problem 2.
Switch the meter ON and
observe the display.
If the display reads zero, the
probe and cable circuitry are
alright. Service probe and
change membrane.
If the display does not read
zero, but some other value,
49
Instruction Manual
CyberScan DO 110
then there is probably
moisture somewhere. See
Problem 2.
With membrane cap
removed and probe
internals thoroughly dry, the
reading from the probe is
not zero and/or is erratic.
Moisture has entered the
system – either into the probe
itself or at junctions or points in
the cable. This moisture creates
a secondary galvanic action in
addition to that produced by the
probe and results in non-zero or
erratic readings.
Locate the source of
moisture by process of
elimination. If moisture has
entered a junction box or a
cable joint, thoroughly dry out
the area and take measures
to prevent reoccurrence.
It is not possible to calibrate
the probe in air – the
display will not read high
enough after fully adjusting
the offset.
Probe has dried out – no
electrolyte inside.
Service probe and change
membrane. Use a stiff nylon
brush to remove the oxide
built-up from the anode. Do
not use a wire brush. It is
only necessary to remove the
loose oxide layer. If it is
suspected that the anode is
badly corroded, replace with
a new DO probe. Remember
to tighten the nut under the
anode before fitting a new
anode.
Probe is overdue for servicing –
excessive build-up of anode
oxide.
A deposit has built-up on the
silver cathode, which is
inhibiting the reduction of
oxygen at its surface.
If it is suspected that a
deposit is coating the silver
cathode, clean the cathode
with 400 grit wet/dry emery
paper or with some scouring
powder. The deposit is
sometimes visible as a
brownish stain on the surface
of the cathode.
Display values are erratic
when membrane is lightly
touched. Membrane has
bulged outwards.
The membrane has been
damaged.
If the membrane has been
damaged change it and
service the probe.
NOTE: The cathode must not be polished – the surface must remain dull
(do not use a wire brush).
